Multiplayer-only demo version of Battlefield 1942, released on August 2002.
If you want to fix the server list (which doesn't works due to the final shutdown of GameSpy in 2014), go to your "hosts" file (located at "$DRIVE:/WINDOWS/System32/drivers/etc") and add at the end a new line with the following:
157.245.212.59 master.gamespy.com
You need to open your notepad as administrator or else you will not be able to save changes.
For server hosters, please also forward UDP query port 23000 to have your server listed on the Internet.
